CEMENTING DEVICE.

Specification of Letters Patent. Patented Sept, 23, 1919.

Application filed June 11, 1919. Serial No. 303,402. I j

.especially that used as inner tubes for tires.

It has been found, with devices hitherto in use for the purpose ofcementing the edge of a traveling sheet of material, that the extremeouter edge would frequently not be treated with the cementing liquidowing to its meandering motion, its unevenness or to its tendencytocurl, and furthermore, it sometimes happened that so much liquid wasapplied that it would get on the side of the material which it was notdesired to cement.

It is, accordingly, an object of my invention to provide a devicewherein the several objections above referred to will be overcome oravoided.

A further object of my invention has been to provide a simple devicethat will uniformly apply a film of liquid to the edge of a moving stripof material without allowing the liquid to get on the wrong side of thematerial and one which will compensate for any unevenness of travel ofthe material, or any curl at the edge thereof.

In the drawings, wherein I have illustrated the preferred embodiment ofmy invention and in which similar reference numerals designate likeparts:

Figure 1 is a perspective view showing the deviceof my invention inoperation;

Fig.2 is an elevation; and

Fig. 3 is a detail of the cement applying element.

In the specific and particular embodiment of my invention hereindisclosed an upright .10 is bolted or otherwise secured to any suitablesupport, and is provided at its upper end with ears or lugs 11 betweenwhich is mounted a horizontally disposed pinion or t gear 12 having athumb nut 13 secured thereto by which the pinion may be rotated.

A rack 14 having its toothed. surfacelf) in mesh with the pinion 12,isfitted to slide oluble wheel, roll or other suitable element 19 thework-face of which is preferably concaved as shown in Figs. 2 and 3.

More specifically the preferred conformation of the work-face of theroll is that shown in Fig. 3, that is to say, incross-section the lineis straight for a portion of its length, A-+B, it then takes an angle ofapproximately 15 degrees from the point B to the point C, for a lengthsubstantially equal to the width of the skived portion of the strip;from the point C the line rises on a curve of gradually increasing pitchto D, for a purpose that will presently appear.

Arranged below theroll, "or wheel so as to surround the lower partthereof is a re-' ceptacle 21 in which the cement or. other liquid iscontained; the wheel dipping in the liquid as it is revolved byfrictional Contact with the material.

A strip or sheet of material 20 to the edge 20 of which the liquid inthe receptacle 21 is to be applied (specifically a strip of rubbermaterial having a skived edge'20 is caused to travel so that the edge ofthe material is passed inproximity to the upright 10 and the elementcarriedthereby.

edges of the latter mayproject, and thus be engaged by the cementingelement.

The operation of my device isas follows: The strip of material 20 isbrought in place on the conveyer belt 22 and the-rack 14 is adjusted bymeans of the pinion 12 17 sufliciently overhangs the material, to causethe roll 19 to bear by gravity. against the edge of the material, Inother. words the roll issuspendedofi center 'bythe raclg .;10

so that the'point of support 16 of the arnf 14c. The contact of themoving strip 20 with the wheel 19 will, .in operation, cause the wheelto revolve and apply to the edge 21 of the material a film of the liquidcontained in the receptacle in which the wheel dips. Normally the skivedportion 21 of the strip is engaged by the part of the wheel B C, asshown in Fig. 3, but, if the edge of the material should be curved atplaces, the curved portion would nevertheless be cemented by reason ofthe curvature of the wheel face, and by the wheels being pressed againstthe edge by gravity. In the same way if there be any unevenness ofelther 1n the strip itself, or in its travel, the face of the wheel willclosely follow the edge of the material.

While I have shown my device applied to but one edge of the strip 20 itis usually customary to provide a similar device for the opposite edge,and by reversing the direction of travel of the strip, as by passing itover a friction roll or the like, to cement the other side of thematerial at its opposite ed e.

Although I have shown a specific embodiment of my invention and referredto its use in a particular industry, it will be understood that changesand modifications may be made in the device without in any sensedeparting from the essence of the invention as defined by the appendedclaims, and that the device will have utility in many analogous arts.
